Lake Profondo had a depth of 84 feet. Lake Segundo is 5/6 as deep. What is the elevation at the bottom of lake Segundo? (Remember, the elevation is below sea level. Account for this in your answer)

Answer 1

Lake Segundo is 70 feet deep because 84 x (5/6) = <<84*(5/6)=70>>70
The elevation is -70 because it is below sea level.
